Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, and specifically provides a pressure cooking device. Background Art

[0002] At present, electric pressure cookers are loved by many consumers for their speed and multi-functions. In the related art, during the use of electric pressure cookers, the soup after high-pressure stewing will appear to be clear and watery. To solve this problem, it is necessary to produce boiling through continuous exhaust and pressure reduction. Violent boiling will cause more precipitates in the soup, thereby making the soup thicker. However, long-term boiling will bring another problem, that is, the violent boiling generated during the continuous exhaust process will produce a lot of bubbles. If these bubbles cannot be effectively handled, they will overflow from the pot through the exhaust channel with the soup, affecting the user experience. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, one aspect of the utility model provides a pressure cooking device.

[0005] In view of this, the first aspect of the utility model provides a pressure cooking device, which includes a pot assembly, a lid assembly, an exhaust assembly and an anti-overflow assembly. The pot assembly is provided with a cooking cavity; the lid assembly is provided on the pot assembly and can open or close the cooking cavity; the exhaust assembly is provided on the lid assembly, and when the exhaust assembly is in an open state, the cooking cavity can be communicated with the outside of the pressure cooking device through the exhaust assembly; the anti-overflow assembly is communicated with the exhaust assembly, and the anti-overflow assembly includes a shell assembly, an air intake component and a grille assembly, and the shell assembly has a cavity and a first through hole; the air intake component is connected to the shell assembly, and the air intake component is provided with a first channel; the grille assembly is provided in the cavity, and the cavity is divided into at least two anti-overflow cavities, and the at least two anti-overflow cavities are connected; the first channel is communicated with the first anti-overflow cavity of the at least two anti-overflow cavities, and the first through hole is communicated with the second anti-overflow cavity of the at least two anti-overflow cavities, and is communicated with the exhaust assembly through the first through hole; wherein, during the cooking process of the pressure cooking device, the exhaust assembly is in an open state, and there is a pressure difference between the first anti-overflow cavity and the cooking cavity, and the food in the cooking cavity can enter the first anti-overflow cavity under the action of the pressure difference.

[0006] The pressure cooking device provided by the utility model comprises a pot assembly, a cover assembly, an exhaust assembly and an anti-overflow assembly. The pot assembly has a cooking cavity, and food can be accommodated in the cooking cavity so that the pressure cooking device can cook the food.

[0007] The cover assembly is mounted on the pot assembly, and the cover assembly can open or close the cooking cavity. When the cover assembly is mounted on the pot assembly, the cover assembly closes the cooking cavity, and the pressure cooking device performs pressure cooking on the food through the cooking cavity. The cover assembly is separated from the pot assembly to expose the cooking cavity, and food is put into the cooking cavity or taken out of the cooking cavity.

[0008] The exhaust assembly is arranged on the cover assembly. When the exhaust assembly is in the open state, the cooking cavity can be connected to the outside of the pressure cooking device through the exhaust assembly. The gas in the cooking cavity can be exhausted through the exhaust assembly. During the pressure cooking process, as the temperature rises, the pressure in the cooking cavity will also increase, and some excess gas will be generated. The gas can be exhausted in time through the exhaust assembly to ensure the pressure in the cooking cavity is stable.

[0009] The overflow prevention component is connected to the exhaust component, and the gas discharged from the exhaust component can be processed by the overflow prevention component. The steam discharged to the exhaust component is processed by the overflow prevention component, and is pure steam without bubble overflow. Specifically, the overflow prevention component includes a shell component, an air inlet component and a grille component.

[0010] The shell component is the main structural component of the anti-overflow component, and the shell component has a cavity and a first through hole.

[0011] The air intake component is connected to the shell assembly, and is provided with a first channel. The air intake component is used for allowing steam or steam with soup to enter. Specifically, the steam or steam with soup can enter the first channel of the air intake component.

[0012] The grille assembly is arranged in the cavity, dividing the cavity into at least two overflow prevention cavities, at least two overflow prevention cavities are connected, the first channel is connected to the first overflow prevention cavity of the at least two overflow prevention cavities, and the first through hole is connected to the second overflow prevention cavity of the at least two overflow prevention cavities.

[0013] During the cooking process of the pressure cooking device, the exhaust assembly is in an open state, and there is a pressure difference between the first anti-overflow cavity and the cooking cavity. The food in the cooking cavity can enter the first anti-overflow cavity under the action of the pressure difference. Specifically, the food enters the first anti-overflow cavity of at least two anti-overflow cavities through the first channel. In the above process, on the one hand, under the action of the pressure difference, the speed of the food entering the first anti-overflow cavity through the first channel can be increased. During the high-speed flow of the food, the high-pressure passage formed by the first channel emulsifies the food passing through, making the soup more rich and the taste of the food better. On the other hand, because the food flows through the first channel, only steam or steam with soup can flow into the first anti-overflow cavity through the first channel, and other solid substances of the food, such as food residues, cannot enter the first channel, and then cannot enter the first anti-overflow cavity. Therefore, the blockage of the first channel and the first anti-overflow cavity can be avoided, and the selection of the substances entering the first anti-overflow cavity is realized, ensuring the anti-overflow and bubble-breaking effect.

[0014] The steam passes through the first channel and enters the first overflow prevention cavity, and the bubbles are broken by the pressure difference formed in the process of entering the large cavity from the small-aperture channel, and the pressure difference formed between the first overflow prevention cavity and the cooking cavity. After the steam enters, the bubbles are broken multiple times through the holes on the grid component. The number of overflow prevention cavities is at least two, which extends the movement path of the steam and achieves a better overflow prevention and bubble breaking effect. Ultimately, the steam discharged through the first through hole is pure steam, and no bubbles overflow from the first through hole. The overflow prevention component can achieve a better overflow prevention effect.

[0015] In addition, the pressure cooking device in the above technical solution provided by the utility model may also have the following additional technical features:

When the pressure cooking appliance is in use, the steam moves in the cavity through the grille assembly, enters different anti-overflow cavities, and finally flows into the second anti-overflow cavity of the at least two anti-overflow cavities, and then is discharged through the first through hole, thereby breaking the steam bubbles, so that the steam discharged through the first through hole is pure steam.

[0018] On the one hand, the air intake component is connected to the shell so that the air intake component is stably fixed through the shell, and the first channel of the air intake component can be connected to the first overflow prevention chamber of at least two overflow prevention chambers to transport steam or steam with soup to the first overflow prevention chamber of at least two overflow prevention chambers.

[0023] After the steam or steam with soup flows into the first anti-overflow chamber through the first channel, it continues to move through the first gap between the grille assembly and the first cover body, enters into other anti-overflow chambers, and finally flows into the second anti-overflow chamber among the at least two anti-overflow chambers, and then is discharged through the first through hole.

[0024] During the flow of steam or steam with soup, it flows through the first gap through multiple anti-overflow cavities, with a longer moving path and better anti-overflow and bubble-breaking effects. Ultimately, the steam discharged through the first through hole is pure steam, and no bubbles overflow from the first through hole. The pressure cooking appliance can achieve better anti-overflow effects.

[0025] The utility model enables at least two overflow prevention chambers to be connected via a first gap, and the first gap is formed by a grille component and a first cover body, thereby achieving the connection between at least two overflow prevention chambers with a simple structure without complicatedly setting the shape of the grille component.

[0029] During the flow of steam or steam with soup, it flows through multiple anti-overflow cavities through the second gap, with a longer moving path and better anti-overflow and bubble-breaking effect. Ultimately, the steam discharged through the first through hole is pure steam, and no bubbles overflow from the first through hole. The anti-overflow component can achieve better anti-overflow effect.

[0030] The utility model enables at least two overflow prevention chambers to be connected via a second gap, and the second gap is formed by the grille component and the shell, thereby enabling the connection between at least two overflow prevention chambers to be achieved with a simple structure without the need to complicate the shape of the grille component.

[0032] In this technical solution, the grille assembly is provided with a second through hole, and at least two overflow prevention cavities are connected through the second through hole. When the steam flows from the first channel to the first through hole, the plurality of partitions block the flow of the steam. When the steam enters the cavity, bubbles are formed due to the pressure difference between the inside and the outside. At this time, the formed bubbles are broken by the grille provided with the second through hole, thereby achieving the effect of overflow prevention and bubble breaking.

[0033] In some technical solutions of the present utility model, optionally, the diameter of the second through hole is greater than or equal to 1.5 mm and less than or equal to 8 mm.

[0036] In this technical solution, the bottom wall of the shell assembly is also provided with a reflux hole, which is connected to the cavity. The pressure cooking device also includes a reflux plug, which is provided in the reflux hole and can block or open the reflux hole. When the reflux plug blocks the reflux hole, the liquid left in the cavity after multiple bubble breaking can be accumulated. When the reflux plug opens the reflux hole, the liquid left in the cavity after multiple bubble breaking will flow back into the pot assembly of the pressure cooking device. After being emulsified in the cavity, this part of the liquid can further enhance the flavor of the food in the cooking cavity of the pressure cooking device and enhance the cooking effect.

[0037] In some technical schemes of the present invention, optionally, the reflux plug includes: a sealing portion, which is arranged on the outside of the shell assembly and opposite to the reflux hole; a guide portion, a first end of the guide portion is connected to the sealing portion and is passed through the reflux hole, and the second end of the guide portion is located in the cavity; a limiting portion, which is connected to the second end of the guide portion and protrudes from the side wall of the guide portion; wherein the length of the guide portion is greater than the thickness of the bottom wall of the shell assembly.

[0039] The first end of the guide part is connected to the blocking part and is inserted into the reflux hole. The second end of the guide part is located in the cavity. The guide part can smoothly insert the reflux plug into the reflux hole as a whole.

[0040] The limiting portion is connected to the second end of the guiding portion and protrudes from the side wall of the guiding portion, so that the guiding portion is stably arranged in the reflux hole.

[0043] In the technical solution, on the one hand, the application defines the length of the first channel, which is greater than or equal to 0 and less than or equal to 150 mm. Steam or steam with soup enters the first anti-overflow chamber through the first channel, and the value of the length of the first channel is greater than or equal to 0 mm and less than or equal to 150 mm, which can better emulsify the steam or steam with soup, and the emulsification effect is better.

[0044] On the other hand, the diameter of the first channel is greater than or equal to 1.5 mm and less than or equal to 20 mm. The utility model sets the diameter size of the first channel, and the value range of the diameter of the first channel is 1.5 mm to 20 mm. The first channel can ensure emulsification and anti-overflow effects without being easily blocked.

The filter component is provided with a third through hole, which is connected to the first channel, and the diameter of the third through hole is smaller than the diameter of the first channel. The filter component can filter solid matter in the food. Since the diameter of the third through hole is smaller than the diameter of the first channel, the solid matter can be directly intercepted outside the first channel to avoid clogging of the first channel.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0077] Refer to the following Figures 1 to 13 A pressure cooking appliance 10 according to some embodiments of the present invention is described.

[0078] like Figure 1 , Figure 5 and Fig.13 As shown, in one embodiment of the present invention, a pressure cooking device 10 is provided, and the pressure cooking device 10 includes a pot assembly 240, a lid assembly 200, an exhaust assembly 220 and an anti-overflow assembly 100.

[0079] The pressure cooking device 10 proposed in the present invention comprises a pot assembly 240, a cover assembly 200, an exhaust assembly 220 and an anti-overflow assembly 100. The pot assembly 240 has a cooking cavity 242, and food can be accommodated in the cooking cavity 242 so that the pressure cooking device 10 can cook the food.

[0080] The cover assembly 200 is placed on the pot assembly 240, and the cover assembly 200 can open or close the cooking cavity 242. When the cover assembly 200 is placed on the pot assembly 240, the cover assembly 200 closes the cooking cavity 242, and the pressure cooking device 10 performs pressure cooking on the food through the cooking cavity 242. The cover assembly 200 is separated from the pot assembly 240 to expose the cooking cavity 242, and food is put into the cooking cavity 242 or taken out of the cooking cavity 242.

[0081] The exhaust assembly 220 is disposed on the cover assembly 200. When the exhaust assembly 220 is in an open state, the cooking cavity 242 can be connected to the outside of the pressure cooking device 10 through the exhaust assembly 220. The gas in the cooking cavity 242 can be exhausted through the exhaust assembly 220. During the pressure cooking process, as the temperature increases, the pressure in the cooking cavity 242 will also increase, and some excess gas will be generated. The gas can be exhausted in time through the exhaust assembly 220 to ensure that the pressure in the cooking cavity 242 is stable.

[0082] The overflow prevention assembly 100 is connected to the exhaust assembly 220, and the gas discharged from the exhaust assembly 220 can be processed by the overflow prevention assembly 100. The steam discharged to the exhaust assembly 220 is processed by the overflow prevention assembly 100 to be pure steam without bubble overflow. Specifically, the overflow prevention assembly 100 includes a shell assembly 110, an air intake assembly and a grille assembly 140.

[0083] The shell component 110 is a main structural component of the anti-overflow component 100 , and the shell component 110 has a cavity 116 and a first through hole 124 .

[0084] The air intake component 130 is connected to the shell assembly 110 . The air intake component 130 is provided with a first channel 132 . The air intake component 130 is used to allow food, ie, steam or steam with soup, to enter. Specifically, food can enter the first channel 132 of the air intake component 130 .

[0085] The grille assembly 140 is disposed in the cavity 116, dividing the cavity 116 into at least two anti-overflow cavities 118, and the at least two anti-overflow cavities 118 are connected. The first channel 132 is connected to the first anti-overflow cavity 120 of the at least two anti-overflow cavities 118, and the first through hole 124 is connected to the second anti-overflow cavity 122 of the at least two anti-overflow cavities 118.

[0086] During the cooking process of the pressure cooking device 10, the exhaust assembly 220 is in an open state, and there is a pressure difference between the first anti-overflow cavity 120 and the cooking cavity 242. The food in the cooking cavity 242 can enter the first anti-overflow cavity 120 under the action of the pressure difference. Specifically, the food enters the first anti-overflow cavity 120 of the at least two anti-overflow cavities 118 through the first channel 132. In the above process, on the one hand, under the action of the pressure difference, the speed of the food entering the first anti-overflow cavity 120 through the first channel 132 can be increased. During the high-speed flow of the food, the high-pressure passage formed by the first channel 132 emulsifies the food passing through, making the soup more concentrated, and the taste of the food cooked by the pressure cooking device 10 is better. On the other hand, since the food flows through the first channel 132, only steam or steam with soup can flow into the first anti-overflow chamber 120 through the first channel 132, and other solid substances in the food, such as food residues, cannot enter the first channel 132, and thus cannot enter the first anti-overflow chamber 120, thereby avoiding blockage of the first channel 132 and the first anti-overflow chamber 120, and realizing the selection of substances entering the first anti-overflow chamber 120, thereby ensuring the anti-overflow and bubble-breaking effect.

[0087] Steam enters the first anti-overflow cavity 120 through the first channel 132. The pressure difference formed by the process of entering the large cavity 116 from the small-aperture channel and the pressure difference formed between the first anti-overflow cavity 120 and the cooking cavity 242 will break the bubbles. After entering, the steam will be broken multiple times through the holes on the grid component. The number of anti-overflow cavities 118 is at least two, thereby extending the movement path of the steam, and the anti-overflow and bubble breaking effect is better. Finally, the steam discharged through the first through hole 124 is pure steam, and no bubbles overflow from the first through hole 124. The anti-overflow component 100 can achieve a better anti-overflow effect.

[0088] The pressure cooking device 10 proposed in the utility model can be specifically an electric pressure cooker. During the cooking process of the electric pressure cooker, the anti-overflow component 100 performs anti-overflow and bubble breaking, so that the electric pressure cooker always maintains a slight boiling in the pot during the cooking process, which can improve the cooking effect and also effectively shorten the time for reducing the pressure and opening the lid, avoiding the user from waiting for a long time.

[0089] Specifically, Figure 1 The arrows in the figure show the flow direction of steam when it enters the anti-overflow component 100 during the cooking process of the pressure cooking device 10. Specifically, the steam enters the first anti-overflow chamber 120 through the first channel 132, then passes through the partition 140 to enter the second anti-overflow chamber 122, and then is discharged through the first through hole 124.

[0090] Specifically, Figure 2As shown, there are two air intake components 130 , and the two air intake components 130 are respectively arranged at one end of the shell assembly 110 to achieve two-way air intake and improve the efficiency of steam processing.

[0091] Specifically, Figure 2 The arrows in the figure show the flow direction of steam when it enters the anti-overflow component 100 during the cooking process of the pressure cooking device 10 when there are two air inlet components 130. Specifically, the steam enters the first anti-overflow chamber 120 through the first channels 132 on both sides, then passes through the partition 140 to enter the second anti-overflow chamber 122, and then is discharged through the first through hole 124.

[0092] like Figure 2 , Figure 3 , Figure 4 , Figure 7 and Fig.10 As shown, in some embodiments of the present invention, optionally, the shell assembly 110 includes a shell body 112 and a first cover body 114, wherein the first cover body 114 is connected to the shell body 112, and the first cover body 114 and the shell body 112 enclose a cavity 116; the air intake component 130 is connected to the shell body 112; or the air intake component 130 is connected to the first cover body 114.

[0093] In this embodiment, the shell assembly 110 specifically includes a shell body 112 and a first cover body 114, wherein the first cover body 114 is connected to the shell body 112, and the first cover body 114 and the shell body 112 enclose a cavity 116, thereby accommodating the grille assembly 140, and separating the cavity 116 into at least two anti-overflow cavities 118. When the anti-overflow assembly 100 is in use, the steam moves in the cavity 116 through the grille assembly 140, enters different anti-overflow cavities 118, and finally flows into the second anti-overflow cavity 122 of the at least two anti-overflow cavities 118, and then is discharged through the first through hole 124, thereby breaking the steam bubbles, so that the steam discharged through the first through hole 124 is pure steam.

[0094] On the one hand, if Figure 2 , Figure 3 and Figure 7 As shown, the air intake component 130 is connected to the shell 112 so that the air intake component 130 is stably fixed through the shell 112, and the first channel 132 of the air intake component 130 can be connected to the first anti-overflow chamber 120 of at least two anti-overflow chambers 118 to transport steam or steam with soup to the first anti-overflow chamber 120 of at least two anti-overflow chambers 118.

[0095] On the other hand, Fig.10As shown, the air intake component 130 is connected to the first cover body 114, so that the air intake component 130 is stably fixed through the first cover body 114, and the first channel 132 of the air intake component 130 can be connected to the first anti-overflow chamber 120 of at least two anti-overflow chambers 118, and transport steam or steam with soup to the first anti-overflow chamber 120 of at least two anti-overflow chambers 118.

[0096] Specifically, the first channel 132 of the air intake component 130 is disposed on the surface of the first cover 114 .

[0097] The utility model is provided with an air intake component 130 which can be connected to the shell body 112 on one hand, and can be connected to the first cover body 114 on the other hand. The air intake component 130 can be arranged in various ways, and the air intake component 130 can be flexibly arranged according to installation requirements, so that the anti-overflow component 100 can be applicable to a variety of pressure cooking appliances 10 and has a wider range of uses.

[0098] Specifically, the housing 112 and the first cover 114 are both circular discs, so that the anti-overflow assembly 100 can be suitable for being installed on the first cover 114 of the pressure cooking appliance 10 .

[0099] In some embodiments of the present invention, optionally, the grille assembly 140 is connected to the shell 112, and a first gap is defined between the grille assembly 140 and the first cover body 114; at least two anti-overflow cavities 118 are connected via the first gap.

[0100] In this embodiment, the grille assembly 140 is connected to the housing 112, so that the grille assembly 140 can be stably disposed in the cavity 116. A first gap is provided between the grille assembly 140 and the first cover 114, and at least two anti-overflow cavities 118 are connected through the first gap.

[0101] After the steam or steam with soup flows into the first anti-overflow chamber 120 through the first channel 132, it continues to move through the first gap between the grille assembly 140 and the first cover body 114, enters into other anti-overflow chambers 118, and finally flows into the second anti-overflow chamber 122 of at least two anti-overflow chambers 118, and then is discharged through the first through hole 124.

[0102] During the flow of steam or steam with soup, it flows through the first gap through multiple anti-overflow cavities 118, with a longer moving path and a better anti-overflow and bubble-breaking effect. Finally, the steam discharged through the first through hole 124 is pure steam, and no bubbles overflow from the first through hole 124. The anti-overflow component 100 can achieve a better anti-overflow effect.

[0103] The utility model enables at least two anti-overflow cavities 118 to be connected via a first gap, and the first gap is formed by the grille component 140 and the first cover body 114, thereby achieving connection between at least two anti-overflow cavities 118 with a simple structure without complicatedly setting the shape of the grille component 140.

[0104] In some embodiments of the present invention, optionally, the grille assembly 140 is connected to the first cover body 114, and a second gap is provided between the grille assembly 140 and the shell 112; at least two anti-overflow cavities 118 are connected through the second gap.

[0105] In this embodiment, the grille assembly 140 is connected to the first cover 114, so that the grille assembly 140 can be stably disposed in the cavity 116. A second gap is provided between the grille assembly 140 and the housing 112, and at least two anti-overflow cavities 118 are connected through the second gap.

[0106] After the steam or steam with soup flows into the first anti-overflow chamber 120 through the first channel 132, it continues to move through the second gap between the grille assembly 140 and the shell 112, enters into other anti-overflow chambers 118, and finally flows into the second anti-overflow chamber among at least two anti-overflow chambers 118, and then is discharged through the first through hole 124.

[0107] During the flow of steam or steam with soup, it flows through the second gap through multiple anti-overflow cavities 118, with a longer moving path and a better anti-overflow and bubble-breaking effect. Finally, the steam discharged through the first through hole 124 is pure steam, and no bubbles overflow from the first through hole 124. The anti-overflow component 100 can achieve a better anti-overflow effect.

[0108] The utility model enables at least two anti-overflow cavities 118 to be connected via a second gap, and the second gap is formed by the grille component 140 and the shell 112, thereby achieving the connection between at least two anti-overflow cavities 118 with a simple structure without complicatedly setting the shape of the grille component 140.

[0109] like Figure 6 As shown, in some embodiments of the present invention, optionally, the grille assembly 140 is provided with a second through hole 148 ; at least two anti-overflow cavities 118 are connected through the second through hole 148 .

[0110] In this embodiment, the grille assembly 140 is provided with a second through hole 148, and at least two anti-overflow cavities 118 are connected through the second through hole 148. When the steam flows from the first channel 132 to the first through hole 124, the plurality of partitions 142 blocks the flow of the steam, and when the steam enters the cavity 116, bubbles are formed due to the pressure difference between the inside and the outside. At this time, the formed bubbles are broken by the grille provided with the second through hole 148, thereby achieving the effect of anti-overflow and bubble breaking.

[0111] In some embodiments of the present invention, optionally, the diameter of the second through hole 148 is greater than or equal to 1.5 mm and less than or equal to 8 mm.

[0112] In this embodiment, the utility model sets the specific size of the second through hole 148 to be greater than or equal to 1.5 mm and less than or equal to 8 mm. The second through hole 148 on the grille assembly 140 is a through hole structure for connecting at least two anti-overflow cavities 118 and breaking the bubbles formed. The smaller the diameter of the second through hole 148, the better the bubble breaking and overflow prevention effect, but the smaller diameter makes the size of the second through hole 148 too small, which is easy to be blocked and difficult to clean after being blocked.

[0113] The present application comprehensively considers the requirements of bubble breaking and anti-clogging, and sets the diameter of the second through hole 148 to be greater than or equal to 1.5 mm and less than or equal to 8 mm, so that the second through hole 148 can achieve a better bubble breaking effect and is not easy to be clogged.

[0114] Specifically, the diameter of the second through hole 148 may be 1.5 mm, and the diameter of the second through hole 148 may also be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, or 8 mm.

[0115] like Figure 1 , Figure 8 and Fig. 9 As shown, in some embodiments of the present invention, optionally, the bottom wall of the shell assembly 110 is provided with a reflux hole 126 , and the overflow prevention assembly 100 further includes: a reflux plug 150 , which is disposed in the reflux hole 126 and can block or open the reflux hole 126 .

[0116] In this embodiment, the bottom wall of the shell assembly 110 is further provided with a reflux hole 126, and the reflux hole 126 is connected to the cavity 116. The anti-overflow assembly 100 further includes a reflux plug 150, which is disposed in the reflux hole 126 and can block or open the reflux hole 126. When the reflux plug 150 blocks the reflux hole 126, the liquid left in the cavity 116 after multiple bubble breaking can be accumulated. When the reflux plug 150 opens the reflux hole 126, the liquid left in the cavity 116 after multiple bubble breaking will flow back into the pot of the pressure cooking device 10. After being emulsified in the cavity 116, this part of the liquid can further enhance the flavor of the soup in the pot of the pressure cooking device 10 and enhance the cooking effect.

[0117] The reflux plug 150 can be opened by gravity. The bottom wall of the shell component 110 is provided with a reflux hole 126. The reflux plug 150 is arranged in the reflux hole 126. The cavity 116 is located above the reflux hole 126 and the reflux plug 150. The reflux plug 150 blocks the reflux hole 126. When the anti-overflow component 100 is working, when the gravity of the liquid left in the cavity 116 after multiple bubble breaking is greater than the force generated when the reflux plug 150 is set in the reflux hole 126, the reflux plug 150 will be squeezed out of the reflux hole 126, and then this part of the liquid will flow back into the pot component 240 of the pressure cooking device 10. After this part of the liquid is emulsified by the cavity 116, it can further enhance the flavor of the soup in the cooking cavity 242 and enhance the cooking effect.

[0118] In some embodiments of the present invention, optionally, the reflux plug 150 includes: a sealing portion 152, which is arranged on the outside of the shell assembly 110 and opposite to the reflux hole 126; a guide portion 154, wherein the first end 156 of the guide portion 154 is connected to the sealing portion 152 and is passed through the reflux hole 126, and the second end 158 of the guide portion 154 is located in the cavity 116; a limiting portion 159, which is connected to the second end 158 of the guide portion 154 and protrudes from the side wall of the guide portion 154; wherein the length of the guide portion 154 is greater than the thickness of the bottom wall of the shell assembly 110.

[0119] In this embodiment, the reflux plug 150 specifically includes a blocking portion 152, a guide portion 154 and a stopper portion 159. The blocking portion 152 is disposed outside the shell assembly 110, opposite to the reflux hole 126, and is used to block the reflux hole 126 outside the shell assembly 110.

[0120] The first end 156 of the guide portion 154 is connected to the blocking portion 152 and is inserted into the reflux hole 126 . The second end 158 of the guide portion 154 is located in the cavity 116 . The guide portion 154 allows the reflux plug 150 to be smoothly inserted into the reflux hole 126 as a whole.

[0121] The limiting portion 159 is connected to the second end 158 of the guiding portion 154 and protrudes from the side wall of the guiding portion 154 , so that the guiding portion 154 is stably disposed in the reflow hole 126 .

[0122] The length of the guide portion 154 is greater than the thickness of the bottom wall of the shell assembly 110 , ensuring that the return hole 126 is completely blocked.

[0123] Specifically, when the reflux plug 150 is used to block the reflux hole 126, the guide portion 154 and the limiting portion 159 are inserted into the reflux hole 126. After insertion, the limiting portion 159 is limited in the cavity 116. The guide portion 154 is arranged in the reflux hole 126, and the blocking portion 152 is located on the outside of the shell assembly 110 to externally seal the reflux hole 126.

[0124] When the reflux hole 126 is opened, a force may be applied to the blocking portion 152 to move the reflux plug 150 out of the reflux hole 126 as a whole.

[0125] like Figure 1 As shown, in some embodiments of the present invention, optionally, the length of the first channel 132 ( Figure 1 The L in the figure is greater than or equal to 0 mm and less than or equal to 150 mm.

[0126] In this embodiment, the food enters the first anti-overflow chamber 120 through the first channel 132. The length of the first channel 132 is greater than or equal to 0 mm and less than or equal to 150 mm. The steam or steam with soup in the food can be better emulsified, and the emulsification effect is better.

[0127] like Fig.10 As shown, when the length dimension of the first channel 132 is 0 mm, this length dimension is a special arrangement form of the first channel 132 . At this time, there is no separately exposed channel structure, and the air intake structure is directly opened on the wall surface of the shell component 110 .

[0128] The longer the first channel 132 is, the better the emulsification effect is. However, the first channel 132 and the air inlet component 130 should be installed conveniently. The utility model considers the use scenarios of the existing pressure cooking apparatus 10 and the size of the existing pressure cooking apparatus 10, and sets the maximum length of the first channel 132 to 150 mm, so that the installation of the first channel 132 is more convenient, the processing and cleaning of the first channel 132 are easier, and food residue is less likely to appear in the first channel 132. The anti-overflow assembly 100 can be applied to more types of pressure cooking apparatuses 10 and more types of pot covers.

[0129] Specifically, the length of the first channel 132 may be 10 mm, or may be 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, or 150 mm.

[0130] In some embodiments of the present invention, optionally, the length of the first channel 132 is greater than or equal to 0.1 mm and less than or equal to 100 mm.

[0131] In this embodiment, the present application limits the length of the first channel 132, which is greater than or equal to 0.1 mm and less than or equal to 100 mm. The food steam or steam with soup enters the first anti-overflow chamber 120 through the first channel 132. The first channel 132 within the above length range can emulsify the steam or steam with soup better, and the emulsification effect is better.

[0132] The minimum length of the first channel 132 is 0.1 mm, and the maximum length of the first channel 132 is 100 mm. For example, the length of the first channel 132 is 0.1 mm, 0.2 mm, 1 mm, 1.5 mm, 5 mm, 10 mm, 15 mm, 25 mm, 50 mm, 80 mm, 85 mm, 90 mm or 100 mm, etc. In this way, the length of the first channel 132 is moderate, which prevents the length of the first channel 132 from being too short and the time for accelerating the fluid medium from being too short, and prevents the length of the first channel 132 from being too long and causing an increase in the volume of the anti-overflow component 100 or affecting the flow of the fluid medium.

[0133] like Figure 1 As shown, in some embodiments of the present invention, optionally, the diameter of the first channel 132 ( Figure 1 D) is greater than or equal to 1.5 mm and less than or equal to 20 mm.

[0134] In this embodiment, the utility model sets the diameter size of the first channel 132, and the diameter of the first channel 132 ranges from 1.5 mm to 20 mm. The first channel 132 can ensure the emulsification and anti-overflow effects without being easily blocked.

[0135] Specifically, in the process of setting the diameter of the first channel 132, the utility model takes into account that a smaller diameter of the first channel 132 has better effects on emulsification and bubble breaking, but a too small diameter will cause food residues to block the first channel 132 when discharged with the steam, and a too small diameter will make the processing of the first channel 132 more difficult. Therefore, the value range of the diameter of the first channel 132 is not less than 1.5 mm. In addition, as the diameter of the first channel 132 increases, the effect of emulsification and bubble breaking and overflow prevention will become worse. Therefore, the diameter of the first channel 132 does not exceed 20 mm to ensure the emulsification and overflow prevention effects.

[0136] Specifically, the diameter of the first channel may be 1.5 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, or 20 mm.

[0137] In some embodiments of the present invention, optionally, the diameter of the first channel 132 is greater than or equal to 0.1 mm and less than or equal to 10 mm. In this embodiment, the diameter of the first channel 132 is between 0.1 mm and 10 mm. Exemplary. The diameter of the first channel 132 is 0.1 mm, 0.2 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc. In this way, it is convenient to strengthen the collision between fat and / or protein and emulsify the food, and it can also ensure that the food can flow through the first channel 132 in large quantities.

[0138] In some embodiments of the present invention, optionally, the diameter of the first channel 132 is greater than or equal to 10 mm and less than or equal to 20 mm.

[0139] In this embodiment, the diameter of the first channel 132 is between 10 mm and 20 mm. Preferably, the diameter of the first channel 132 is between 2 mm and 5 mm. Exemplarily, the diameter of the first channel 132 is 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm or 20 mm, etc. By setting the diameter of the first channel 132 as above, the collision between fat and / or protein can be strengthened, and the food can be ensured to flow through the first channel in large quantities.

[0140] In some embodiments of the present invention, optionally, the diameter of the first channel 132 is less than 100 micrometers.

[0141] In this embodiment, the diameter of the first channel 132 is less than 100 micrometers. For example, the diameter of the first channel 132 is 20 micrometers, 99 micrometers, 95 micrometers, or 50 micrometers.

[0142] Fat types are divided into three particle sizes: below 50 microns, 50 microns to 100 microns, and above 100 microns. Among them, fat with a particle size of 100 microns and below is soluble in water. The diameter of the first channel 132 is less than 100 microns. After the oil dissolved in the food passes through the first channel 132, it is continuously collided into particles smaller than 100 microns. At the same time, the flow rate of the fluid medium is increased. Under the pressure difference condition, the flow rate of the fluid medium will be greatly improved. The fat and protein in the soup will continuously collide and squeeze in the path, promoting protein to wrap fat or fat to wrap protein or water molecules, thereby achieving emulsification of the food.

[0143] In some embodiments of the present invention, optionally, the length of the first channel 132 is greater than or equal to 0 mm and less than or equal to 150 mm, and the diameter of the first channel 132 is greater than or equal to 1.5 mm and less than or equal to 20 mm.

[0144] In this embodiment, the utility model sets both the length and diameter of the first channel 132. The length of the first channel 132 is greater than or equal to 0 mm and less than or equal to 150 mm, and the diameter of the first channel 132 is greater than or equal to 1.5 mm and less than or equal to 20 mm. The first channel 132 is not easily blocked, and the emulsification and overflow prevention effects are improved.

[0145] In some embodiments of the present invention, optionally, a ratio of the length of the first channel 132 to the diameter of the first channel 132 is greater than or equal to 0 and less than or equal to 10.

[0146] In this embodiment, for the length of the first channel 132 and the diameter of the first channel 132, the utility model is set to a ratio of the length of the first channel 132 to the diameter of the first channel 132 greater than or equal to 0, and less than or equal to 10. Within this ratio, the first channel 132 can achieve the best emulsification and anti-overflow bubble breaking effect on steam. Exemplarily, the ratio of the length of the first channel 132 to the diameter of the first channel 132 can be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10.

[0147] In this embodiment, optionally, a ratio of the length of the first channel 132 to the diameter of the first channel 132 is greater than or equal to 1.

[0148] In this embodiment, the ratio of the length of the first channel 132 to the diameter of the first channel 132 is greater than or equal to 1. Preferably, the ratio of the length of the first channel 132 to the diameter of the first channel 132 is greater than 3. In this way, the food flows through the first channel 132 for a longer time, so that fat and protein can fully collide and squeeze in the first channel 132, and the emulsification effect is better.

[0149] like Figure 3 As shown, in some embodiments of the present invention, optionally, the overflow prevention component 100 also includes: a filter component 160, the filter component 160 is sleeved on the air intake component 130, the filter component 160 is provided with a third through hole 162, the third through hole 162 is connected to the first channel 132, and the diameter of the third through hole 162 is smaller than the diameter of the first channel 132.

[0150] In this embodiment, the overflow prevention component 100 further includes a filter component 160, which is sleeved on the air intake component 130 in the setting position, and the filter component 160 is provided with a third through hole 162, which is connected to the first channel 132, and the diameter of the third through hole 162 is smaller than the diameter of the first channel 132. The solid matter in the food can be filtered by the filter component 160, and because the diameter of the third through hole 162 is smaller than the diameter of the first channel 132, the solid matter can be directly intercepted outside the first channel 132 to prevent the first channel 132 from being blocked.

[0151] Specifically, Figure 3 The arrows in the figure show the flow direction of steam when it enters the anti-overflow component 100 during the cooking process of the pressure cooking device 10. Specifically, the steam enters the first anti-overflow chamber 120 through the first channel 132, then passes through the partition 140 to enter the second anti-overflow chamber 122, and then is discharged through the first through hole 124.

[0152] like Figure 7As shown, in some embodiments of the present invention, optionally, the grille assembly 140 includes: a partition 142, wherein the number of the partitions 142 is multiple, and the multiple partitions 142 are arranged in parallel or crosswise arrangement; a support plate 144, wherein the support plate 144 extends around the multiple partitions 142 and is connected to the multiple partitions 142, and the support plate 144 is provided with a fourth through hole 146, and the fourth through hole 146 is opposite to the first channel 132.

[0153] In this embodiment, with regard to the specific structure of the grille assembly 140 , the present application is configured such that the grille assembly 140 includes a partition 142 and a support plate 144 , and there are multiple partitions 142 , and the multiple partitions 142 are arranged in parallel or in an alternating arrangement to divide the cavity 116 into multiple anti-overflow cavities 118 .

[0154] The support plate 144 is a supporting structural member of the grille assembly 140, and the support plate 144 extends around the plurality of partitions 142 and is connected to the plurality of partitions 142. The plurality of partitions 142 can be connected to form a whole by the support plate 144, so that the plurality of partitions 142 can be arranged easily.

[0155] The support plate 144 is provided with a fourth through hole 146, which is opposite to the first channel 132, so that steam or liquid such as soup can enter the grille assembly 140 and enter the plurality of anti-overflow cavities 118. When steam or steam with soup enters the plurality of anti-overflow cavities 118, bubbles are formed due to the internal and external pressure difference, and the partition plate 142 can break the bubbles, thereby achieving the effect of breaking bubbles and preventing overflow.
